The light weight removable mesh pocket with draw cord is quickly fixed to bike panniers, backpacks or other bags. The mounting set is screwed onto the bag (watertight connection!) and remains there. The mesh pocket can be taken off quickly and easily. The mounting consists of two mounting rails which are screwed to the bag at defined positions. The mesh pocket is safely inserted into these mounting rails. This system allows quick removal and fixing. The mesh pocket is suitable for panniers, backpacks and many other bags. The mounting set is identical with the ORTLIEB outer pocket and bottle cage (both available as accessories), and is therefore compatible with those. Attention: the mesh pocket is not waterproof! The mesh pocket offers additional room for wet or dry clothing, for a helmet, dirty shoes or voluminous grocery shopping. It folds away easily when not needed. A reflector provides safety in the dark or in bad weather conditions.
